The ole 6br.

[andym686]

I'd never heard of the 6BR until ten or so years ago, I was offered a pretty screaming deal on a Model 40XBR rifle chambered in 22 Rem BR. It was a pretty strange duck in this little cow town, and since it came home with me, I joined this forum and started broadening my horizons. jd

Similar story:
I had a rifle I wanted to re-barrel. A local benchrest shooter started telling me about the merits of the 6BR, and I got real interested.
His name was Ed Hartman, from here in Yadkin County, NC. I'm sure some guys on here shot with him.
Sadly, Ed passed away a few years ago. I wish I had met him sooner.

Sure, it’s your fault I had this made anyways, thank you. That rifle has been a PIA for 15+ years. I originally had it built into a 6BR and it never would shoot like a 6BR should, mediocre at best. I then sent to another smith who I’ve used before with good results and had it rechambered to a 6 Dasher, my mistake was using the same barrel. After giving up on the barrel it has sat in the safe for a long time. I’ve been wanting to do something with it, it’s not worth selling, then I saw your model 7 and that was that. I sent this to Zack and ordered a Hawk Hill, 1-17 twist, fluted, Zack did his thing and Sniper Grey worked for the cerakote. I have had two bench sessions. First I shot some 112s Zack gave me and they were .5 Moa five shots. Tried some 125 TGKs and they went into the same hole, same with 125 varmeggedons. I need to retry the 112s now that I have a few rounds down the barrel and it’s breaking in. H4198 is the only powder I’ve used, I still have 16 pounds, I’ll use that until it’s gone. I actually ended up using one of your loads which I thank you again for.

Best part is the rifle is back in good graces, shoots itty bitty and I don’t snear every time I look at it. Can’t wait to thump a yote with it.

WOW !!! Nice. Happy to be helpful with your decision in building the 30BR and with you choosing Zack to get it done. Great to be of help with your load as well. I like to work up a load and let it prove to me that it's good and share with others. And with the 30BR if I can't see 1/4 MOA @ 100 yds. I move along with both my 700 & M-7 rifles. Actually, I don't own a rifle that I have not seen 1/4 MOA with good loads that Zack has built me. I said it yesterday on a thread and I will say it once more. I don't call that luck. I call that precision.

But wait isn't the 6BR just a shortened 308 necked down to 6mm? jackie needs to add it to his list

Kinda sounds like it evolved from 308x1.5 Barnes possibly which is a 308 based wildcat

Either way I’ve wanted a 6BR or variation for years and when I built one I wasn’t disappointed.

 

[ebb]

I am nor sure but I seem to recall that Mike Walker was the dady to the shortened 308

I was waiting for someone to post this, that’s what I’ve always thought

 

[M-61]

Isn't the 308 based off the 30-06? Just askin'

Didn’t it start as a 30-03?

 

[M-61]

I guess you could start with the first metallic cartridge. Without that you have nothing.
Unless you want to wait for ceaseless cartridges.

 

[ebb]

No but you could start with the first with a .473 base.

picked up my 6BR off this forum a few years back, a LH 40x with a Brux barrel. One of my favorites to shoot, learning along the way from the collective wisdom of others I've picked up here

LH Smith didn't the 7x57 come a decade before the 8x57?

Yes, I am pretty sure it did. Germany made mistake of bigger bullet like the US did too. That 7mm round was almost perfect for military use. So was the 6.5. Countries almost got it right two or three times. Brits pre WWI, then US working on the Garand. Then Brits again, post WWII using the FN Fal... US insisted on Nato, 308. FN got goosed up to 308. Now there is a new super cartridge by Sig.....277, a hair smaller than 7mm. Bad timing pre wwi, not enough time to switch away from 30 cal. Garand, 30 cal, just plain bad decision making.

 

[ebb]

The 8x57 may have been necessary with trenches 1000 to 1200 yards away. I wasn't there so i cannot be sure. But the 7x57 sure seems like a winner to me.

6bra at 1525 yards and it wasn’t difficult to get hits. View attachment 1457917

SK, tell us about your rifle. It looks like a very nice set-up! The bipod looks very interesting.

One interesting note about the 6BR is why Mike Walker developed it in the first place.
that being, to compete in Short Range Benchrest. I think the official moniker was “6 mm Remington Benchrest”.

Glenn Newick gave a good history of it in his book, “The Ultimate in Rifle Accuracy.

In this respect, it was a failure. Shooters found that it would not go toe to toe with the 6PPC. True, there were variants where shooters pushed the shoulder back about .100, essentially giving it the same case volume as the 6PPC and about the same accuracy potential. I know several shooters who did this simply because their rifles, based on theRemington 700 or 40x, had a .473 bolt face.

It wasn’t untill Norma came up with their factory offering in longer and heavier bullets to be used in rifles with longer throats did the 6BR find it’s true purpose In life and in the realm of Benchrest at longer distances.

You have to watch the little cases shoot long distance in person to believe it. The 6Br 6BRA 6BRX and the Dasher. My first venture into the BR case was the 7mm and you had to make your own brass. Remington sold 308 brass with no primer hole drilled or a small primer hole. It was up to you to form BR brass out of the 308 cases.

I still have a case left of 6BR without the flash holes.

Remember Red Cornelison shot his way into the first BR class Hall of Fame with his 22 Red Russian. A short BR case with the rim rebated to 222 size and a step in the neck to hold the bullet to the same seating depth. I still have a couple pieces of his brass.

I'll post photos this afternoon.

It is of course the one on the far right. To make the step in the neck is a chore to get the right location. You neck turn the OD from the top of the neck to your desired location. When you size it, it sizes the fat part of the neck leaving a step on the ID for the bullet to sit on. Yes, you seated the bullet by putting it in with your fingers, no neck pressure on the bullet.
